Cannot reproduce the evaluation score of HellaSwag, WiC

[rycont]

I evaluated polyglot-ko-1.3b model with HellaSwag and WiC from KoBEST, and I got different results with paper and model card from huggingface.

Environment

• Few-shot examples: 5
• Model: EleutherAI/polyglot-ko-1.3b
• Metrics: F1(Macro) Score
• Computing: Colab / GPU(T4) Instance

I'm going to share a notebook that I tested with.
https://colab.research.google.com/drive/1lyQQisuB5JzuGk72haSdxXfXP20q4YGr?usp=sharing

1. WiC

The paper says the score 0.486, But I got only 0.4541.

• The paper

params	0-shot	5-shot	10-shot	50-shot
1.3B	0.489	0.486	0.506	0.487

• In my test

hf-causal-experimental (pretrained=EleutherAI/polyglot-ko-1.3b), limit: None, provide_description: False, num_fewshot: 5, batch_size: 8

Task	Version	Metric	Value		Stderr
kobest_wic	0	acc	0.4952	±	0.0141
		macro_f1	0.4541	±	0.0138

2. HellaSwag

The paper says the score 0.526, But I got only 0.3984.

• In the paper

params	0-shot	5-shot	10-shot	50-shot
1.3B	0.525	0.526	0.528	0.543

• In my test

hf-causal-experimental (pretrained=EleutherAI/polyglot-ko-1.3b), limit: None, provide_description: False, num_fewshot: 5, batch_size: 8

Task	Version	Metric	Value		Stderr
kobest_hellaswag	0	acc	0.4020	±	0.0219
		acc_norm	0.5280	±	0.0223
		macro_f1	0.3984	±	0.0218

And I found out a Wandb Report Polyglot-Ko: Open-Source Korean Autoregressive Language Model
, And there's a HellaSwag score that is same as my test, 0.3984.

params	n=0	n=5	n=10	n=50
1.3B	0.4013	0.3984	0.417	0.4416

In case of other models

There are also differences in kakaobrain/kogpt and skt/ko-gpt-trinity-1.2B-v0.5.

• kakaobrain/kogpt
  Note that I tested kakaobrain/kogpt with Int 8 quantized model.

	In the paper (FP16)	In my test (Int8)	In the Wandb Report
CoPA	0.7287	0.7277 (↓0.01%)	0.7287
HellaSwag	0.5833	0.4560 (↓21.82%)	0.456
BoolQ	0.5981	0.6015 (↑0.56%)	-
WiC	0.4775	0.3706 (↓22.38%)	-

• skt/ko-gpt-trinity-1.2B-v0.5

	In the paper	In my test	In the Wandb Report
WiC	0.4313	0.3953	-
HellaSwag	0.5272	0.400	0.4
